3 Vertex Maximum or minimum of the graph For the equation, the vertex is at
4 Identify the vertex for each function 1. f(x) = | 2x – 5 |2. f(x) = | 3x + 6 |3. f(x) = - |x + 1 | - 2
5 Graphing absolute value functions by making a table Find the vertexMake a table of values (at least 5!)Graph the function.
6 Find several ordered pairs for each function. Graph and on the same coordinate plane. Determine the similarities and differences in the two graphs.Find several ordered pairs for each function.x| x – 3 |31245x| x + 2 |–42–31–2–13Example 6-3a
7 Graph the points and connect them. Answer:The domain of both graphs is all real numbers.The range of both graphs isThe graphs have the same shape, but different x-intercepts.The graph of g (x) is the graph of f (x) translated left 5 units.Example 6-3b
